TO ALL WHOM IT MAY CONCERN:

Be it known that I, LYMAN DERBY, of the city, county, and State of NewYork, have invented certain new and useful Improvements in AttachingThills to Axles of Wagons and other vehicles; and'I do hereby declarethat the following is a full description of the same.

The nature of my invention consists in combining with the thill-iron andjack an elastic-strap packing for the purpose of making amanti-rattlingthill-cou'pling and safety-strap. V

But to describe my invention more particularly, I will refer tothe-accompanying drawings,forming a part of this specification, the sameletters of reference, wherever they occur, referring to like parts.

Figure 1 is a side view of the thll-iron as attached to the jack,showing in'red outline the connection with the axle-tree of the vehicle.v y I Figure 2 is a representation of a cut section of the same parts,showing the elastic safety-strap and antirattling packing. I

Letter A represents lthe c1ip-iron for attaching to the axle B, andhaving on the front of it two ear-pieces of metal, C and D, commonlycalled the jackf Through these ear-pieces and the eye E of thethill-iron F, is inserted a bolt, G, for securing the thill and axletogether.

Letter H is an elastic safety-strap, having one end attached to theclip, between the ear-pieces of the jack, by a screw-bolt, I, and theother end secured tothe lower side of the thill-iron by a'pin, J.

The object of this attachment is, first, to make a safety-strap to guardagainst any accidental separation of 4the thill from the axle of thevehicle should thc bolt happen to break or work loose and be lost, andsecond, for

packing the bolt, and thereby prevent all tendency to rattle and workloose, and thus make an anti-rattling as well as a safetythill-coupling. Y

These results will be readily perceived from the operation of theattachment. When the thills are down the safety strap is retracted, butwhen elevated and secured to the harnessed-up horse, the strap is drawnup or stretched! around 'the lower side of the eye of the thill-iron,and thus keeps the bolt firmly packed, as it were, to prevent allrattling of it, or tendency to jar loose the nuton its end.

Having now described my invention, I wili set forth what I claim anddesire to secure by Letters Patent of the United States.

I claimq the combination of the elastic safety-strap H with the clip Aand thill-iron F, substantially -as described and'operating ashereinbeforc set forth.

LYMAN DERBY.
